To all whom it may concern:

Be it known that 1, CHARLES PnnLrs, a citizen of the United States, residing at Oska loosa, in the county of M allablitt and State of Iowa, have invented a certain new and useful Pressurediegulator for Water-Heating Systems, of which the following is a specification.

My object is to provide a device in the na ture of an attachment that may be readily, quickly and easily placed in. communication with a water heating system. Said device is designed. to prevent water from expanding and boiling over until a certain predetermined pressure has been reached, so that the water inthe heating system maybe heated to a point above the boiling point and maintained at such heat without boiling over and discharging through the overflow pipe until after the pressure within the heating system reaches a certain redetermined degree and than the water wil discharge to the overflow tank and after the water has cooled, all that remains in the tank will return to the heating system by means of a check valve located between the valve that leads to the overflow tank and the heating stein.

My invention is designed to be used in the nature of an attachment to be applied to any ordinary water heating system for warming buildings.

My invention consists in the construction, arrajngcment and combination of the attach.- ment with a hot water heating system and an overflow tank as hereinafter more fully set forth, pointed out in my claims and illustrated in the acconu'ianying drawings, in which Figure 1 shows a longitudinal, central, sectional view of a pressure regulator for water heating systems embodying my inventions, and Fig. 2 shows a diagram illustrating a complete heating system with my improved pressure regulator applied thereto.

Referrim tothe accompanying drawings, I have used the reference numeral H) to indicate a hot water heater, 10 a radiator conn cted therewith, and 10 a pipe extending upwardly from the radiator and connected with my improved pressure regulator.

The numeral 1f) indicates the lloor of a buildi and "mounted upon the floor is a water receptacle 11, preferably made of cast i and extends horizontally.

metal and provided with a screw threaded extension 12 at its top. Screwed into the extension 12 is a relatively large pipe 13, for purposes hereinafter made clear, and at the to of the pipe 13 is a reducer 14 screwed to a relatively small pipe 15 which in turn is connected to and communicates with an o en topped overflow tank 16. Mounted within the receptacle 11 is a short. pipe 17 communicating with the heater 10. At the top of the short pipe 17 is a T 18. A screw threaded nipple 19 is connected with one branch of the An elbow 20 is screwed to the nipple 19 and inclines downwardly. A screw threaded nipple 21 connects with the other end of the elbow 20 and also with a check valve casing 22 in which is a check valve 23 of the ordinary construction, arranged to prevent the passage of water from thoT 18 through the valve casing 22 and to 1permit the passage of water in the opposite (lirection. Screwed to the top of theT 18 is a short pipe 24, which pipe is also screwed to the safety valve casing 25 to provide communication between the .T and the safety valve casing. Mounted in the safety valve casing is the valve 136 having a stem 27 which projects into the large pipe 13 above the receptacle 1 1. Located in the pipe 13 is a wcigl'it which rests upon. the valve stem 27 and is contained within the pipe 13, which pipe serves as a guide for the weight and the weight is of such diameter that water may readily pass through the pipe 13 around the weight.

In practical use, it is obvious that my attachment may be assembled ready for use and shifted and handledwith all of the parts connected as required for use and it may be attached to a hot water heating system by simply securing the lower end. of the rece tacle 11 to a water heater and screwing t e reducer 14 to the pi e that communicates with the overflow tanl f.

In practical use and assuming that the Weight 28 is sufliciea'it to hold the valve 26 closed until a pressure of thirty pounds to the s uare inch is applied to the under surface oi the safety vaiv'e 26, it is obvious that the water in. the heater will be heated to a point considerably above the boiling point before steam will generate, because it is well known until the pmssuz s :iX-C- mix mi:-
